Summary
Interferon therapy is useful for decreasing the serum ALT level and improving liver histology in patients with chronic non-A, non-B hepatitis. This study examined the effect of interferon therapy in acute cases of posttransfusion hepatitis C. we report on three cases in which interferon alpha was administered at 100–220.5 million units. HCV RNA became undetectable during interferon administration and the ALT level declined to the normal range. However, after the cessation of the therapy, the ALT level began to fluctuate and HCV RNA reappeared in two patients. We concluded that interferon therapy for the acute phase of posttransfusion hepatitis is useful for suppressing viral replication and quickly improving the ALT level, but it can not always prevent the development of chronic hepatitis. Furthermore, there was a close correlation between the profile of HCV RNA and that of the ALT level, indicating that the replication of HCV plays an important role in liver injury.
